Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent power plants, and particularly relates to a coal humidity detection device for an intelligent power plant. Background Technique

[0002] Building an intelligent power plant is based on intelligent power generation. Through the integration and extension of power generation with other industries, a circular economy is formed to improve the utilization rate of energy and resources, and undertake more functions of environmental protection and social service. It can not only become the capital for power plants to participate in the market economy, but also be the requirement of the new era's ecological environment construction and economic and social development for power enterprises.

[0003] Currently, in the operation of an intelligent power plant, coal input operations are required. A large amount of dust will be generated during the actual transmission of powdered coal. Therefore, water spraying and dust suppression operations are needed. For the adjustment of the water spraying amount, most current operations are to first detect and then adjust through an infrared humidity detector to control the size of the water spraying amount, and then accurately control the coal humidity. However, the installation position of the infrared humidity detector is currently fixed, but the transfer height of the coal on the conveyor belt is not fixed. When the coal on the conveyor belt passes by too high, the coal will directly submerge and cover the infrared humidity detector, causing the infrared humidity detector to lose its detection function and easily damaging the detector. Summary of the Invention

[0004] The purpose of the present invention is to address the above problems and provide a coal humidity detection device for an intelligent power plant.

[0005] To achieve the above object, the present invention provides the following technical solution: A coal humidity detection device for an intelligent power plant includes a fixing plate. On the surface of the fixing plate, two electric push rods are symmetrically and fixedly inserted. The lower output shafts of the two electric push rods are fixedly connected to the same lifting plate. At the lower end of the lifting plate, multiple telescopic rods are symmetrically and fixedly connected. At the lower ends of the multiple telescopic rods, two bottom support plates are symmetrically and fixedly connected. At both ends of the bottom support plate, arc-shaped outwardly expanding plates are connected upward. Between the lower end of the lifting plate and the upper end of the bottom support plate, multiple extrusion rubber sleeves sleeved on the multiple telescopic rods are also fixedly connected. On the upper ends of the two bottom support plates, a U-shaped support plate is fixedly connected. On the upper end of the U-shaped support plate, an infrared humidity detector is fixedly inserted. At the rear end of the side walls on the opposite sides of the U-shaped support plate, a reciprocating lead screw is rotatably connected through a bearing. A moving block is threadedly sleeved on the rod wall of the reciprocating lead screw. At the front side of the moving block, an L-shaped moving plate is fixedly connected. On the upper end of the horizontal part of the L-shaped moving plate, a sponge wiping block is fixedly connected. A rectangular opening is formed on the surface of one of the bottom support plates, and a wheel shaft is rotatably connected in the corresponding rectangular opening. A contact roller is fixedly sleeved on the wheel shaft. A transmission mechanism is connected between the wheel shaft and the reciprocating lead screw.

[0006] In the above-mentioned smart power plant coal humidity detection device, the rear end of the inner wall on the opposite side of the U-shaped support plate is also fixedly connected to a guide slide rod, and the side wall of the moving block is provided with a sliding hole slidably connected to the guide slide rod.

[0007] In the above-mentioned smart power plant coal humidity detection device, the transmission mechanism includes a bearing seat fixedly connected to the upper end of the bottom support plate, a connecting shaft is rotatably sleeved in the bearing seat through the bearing, a driving sprocket is fixedly sleeved on the shaft wall of the wheel axle, one end of the connecting shaft is fixedly connected to a driven sprocket, a transmission chain belt is transmission-connected between the driving sprocket and the driven sprocket, the other end of the connecting shaft is fixedly connected to a driving gear, the outer side of the U-shaped support plate is also rotatably connected to a transmission shaft, the shaft wall of the transmission shaft is fixedly sleeved with a reduction gear meshing with the driving gear, one end of the transmission shaft is also fixedly connected to an incomplete gear, one end of the reciprocating screw rod extends through the U-shaped support plate and is fixedly connected to a transmission gear meshing with the incomplete gear.

[0008] In the above-mentioned smart power plant coal humidity detection device, a protective shell covering the outside of the transmission mechanism is fixedly connected between the upper end of the bottom support plate and the outer side of the U-shaped support plate.

[0009] In the above-mentioned smart power plant coal humidity detection device, the upper end of the U-shaped support plate is fixedly connected with a protective mesh cover that covers the outside of the infrared humidity detector.

[0010] In the above-mentioned smart power plant coal moisture detection device, the outer side of the contact roller is covered with a layer of anti-slip sleeve.

[0011] In the above-mentioned smart power plant coal moisture detection device, a plurality of reinforcing ribs are evenly and fixedly connected at the connection between the U-shaped support plate and the bottom support plate.

[0012] Compared with the prior art, the present invention provides a smart power plant coal moisture detection device, which has the following beneficial effects:

[0013] 1. The smart power plant coal humidity detection device uses a bottom support plate to first adjust the relative placement height of the two bottom support plates through two electric push rods. The squeezing and pushing rubber sleeves always provide a downward squeezing and pushing force to the two bottom support plates, so that the bottom support plates can always be stably in contact with the upper side of the coal material. The infrared humidity detector detects the humidity on the coal surface. As the height of the coal on the conveyor belt changes, the bottom support plate and the arc-shaped expansion plate are automatically raised and lowered by the reverse squeezing force of the coal as the height of the coal changes. With the telescopic rod and the squeezing and pushing rubber sleeves, the detection distance between the infrared humidity detector and the coal is always maintained at one position, avoiding the problem that too high coal can easily submerge the infrared humidity detector and cause damage to it.

[0014] 2. The coal humidity detection device of the intelligent power plant, through the provided contact rollers and sponge wiping blocks, while performing humidity detection, the transmission of coal drives the contact rollers to move. The contact rollers drive the driving sprocket to rotate through the axle, and then drive the driven sprocket to rotate through the transmission connection of the transmission chain belt, thereby driving the connecting shaft to rotate. The connecting shaft drives the driving gear to rotate synchronously, the driving gear drives the reduction gear to rotate, and then drives the incomplete gear to rotate synchronously through the transmission shaft. Then, through the meshing action of the incomplete gear and the transmission gear, the reciprocating lead screw is driven to rotate. Through the threaded socket connection between the reciprocating lead screw and the moving block, the L-shaped moving plate is driven to move, so that the L-shaped moving plate drives the sponge wiping block to move, and the sponge wiping block wipes the detection end of the infrared humidity detector. Because it is driven by an incomplete gear, the wiping is intermittent and does not affect the detection operation of the infrared humidity detector, enabling the entire infrared humidity detector to be automatically cleaned during the operation of the conveyor belt without additional assistance. It operates during work and stops when not working, ensuring that the infrared humidity detector always has good detection performance and is suitable for use in coal powder environments.

[0015] In summary, the present invention keeps the detection distance between the infrared humidity detector and the coal at a constant position, avoiding the problem that excessive coal is likely to submerge the infrared humidity detector and cause damage to it. Description of the Drawings

[0024] Embodiment 2 is based on Embodiment 1 and is as Figure 3 shown. A guide slide bar 18 is also fixedly connected to the rear end of the opposite inner walls of the U-shaped support plate 8. A sliding hole slidably sleeved with the guide slide bar 18 is formed on the side wall of the moving block 11.

[0025] Embodiment 3 is based on Embodiment 1 and is as Figure 2As shown, its transmission mechanism 17 includes a bearing seat 171 fixedly connected to the upper end of the bottom support plate 5, a connecting shaft 172 is rotatably sleeved in the bearing seat 171 through a bearing, a driving sprocket 173 is fixedly sleeved on the shaft wall of the wheel axle 15, one end of the connecting shaft 172 is fixedly connected to a driven sprocket 174, a transmission chain 175 is transmission-connected between the driving sprocket 173 and the driven sprocket 174, the other end of the connecting shaft 172 is fixedly connected to a driving gear 176, a transmission shaft 177 is also rotatably connected to the outer side of the U-shaped support plate 8, a reduction gear 178 meshing with the driving gear 176 is fixedly sleeved on the shaft wall of the transmission shaft 177, one end of the transmission shaft 177 is also fixedly connected to an incomplete gear 179, one end of the reciprocating screw rod 10 passes through and extends out of the U-shaped support plate 8, and is fixedly connected to a transmission gear 1710 meshing with the incomplete gear 179.

[0030] The operating principle of the present invention is described as follows: By providing a bottom support plate 5, first, the relative placement height of the two bottom support plates 5 is adjusted relatively by two electric push rods 2, and the extrusion rubber sleeve 7 is used to always provide a downward extrusion force on the two bottom support plates 5, so that the bottom support plate 5 can stably always contact the upper side of the coal material. The infrared humidity detector 9 detects the humidity on the surface of the coal. As the height of the coal on the conveyor belt changes, the bottom support plate 5 and the arc-shaped outward expansion plate 6 are automatically lifted and lowered with the change of the reverse extrusion force of the coal. The telescopic rod 4 and the extrusion rubber sleeve 7 are used to keep the detection distance between the infrared humidity detector 9 and the coal at a constant position, avoiding the problem that too high coal is likely to submerge the infrared humidity detector and damage it. By providing the contact roller 16 and the sponge wiping block 13, while the humidity is being detected, the movement of the coal drives the contact roller 16 to move. The contact roller 16 drives the driving sprocket 173 to rotate through the axle 15, and then drives the driven sprocket 174 to rotate through the transmission connection of the transmission chain belt 175, thereby driving the connecting shaft 172 to rotate. The connecting shaft 172 drives the driving gear 176 to rotate synchronously. The driving gear 176 drives the reduction gear 178 to rotate, and then drives the incomplete gear 179 to rotate synchronously through the transmission shaft 177. Then, through the meshing action of the incomplete gear 179 and the transmission gear 1710, the reciprocating lead screw 10 is driven to rotate. Through the threaded socket connection of the reciprocating lead screw 10 and the moving block 11, the L-shaped moving plate 12 is driven to move, so that the L-shaped moving plate 12 drives the sponge wiping block 13 to move, and the sponge wiping block 13 wipes the detection end of the infrared humidity detector 9. Because it is driven by the incomplete gear 179, the wiping is intermittent and will not affect the detection operation of the infrared humidity detector 9, and it can ensure that the infrared humidity detector 9 always has good detection performance and is suitable for use in a coal powder environment.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
